Automates patcher tool

Hi,
I've been looking for a tool or script to replace hex sequence in binary file in Windows. Indeed, i found this script :

Code:

---

Imports System.Runtime.CompilerServices
Imports System.IO

Public Class FinduReplaceHex
Private Shared ReadOnly FindHex As Byte() = {&H75, &HF6, &HF3}
Private Shared ReadOnly ReplaceHex As Byte() = {&HA2, &HE3, &H4B}

<MethodImpl(MethodImplOptions.NoInlining)> Private Shared Function DP(sequence As Byte(), position As Integer) As Boolean
If position + FindHex.Length > sequence.Length Then
Return False
End If

For i As Integer = 0 To FindHex.Length - 1
If FindHex(i) <> sequence(position + i) Then
Return False
End If
Next
Return True
End Function

Private Sub Patch_Click(sender As Object, e As EventArgs) Handles Patch.Click

Dim DT As String = Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
Dim FD As Byte() = File.ReadAllBytes(DT & "\App.dll")

For F As Integer = 0 To FD.Length - 1
If Not DP(FD, F) Then
Continue For
End If
For R As Integer = 0 To FindHex.Length - 1
FD(F + R) = ReplaceHex®
Next
Next

If System.IO.File.Exists(DT & "\App.dll") Then
System.IO.File.Move(DT & "\App.dll", DT & "\App.dll.backup")
File.WriteAllBytes(DT & "\App Method 3.dll", FD)

Else
'Write Other Codes

End If

End Sub

End Class

---

The only problem is that I want to be able to use wildcards like this :
Search for F4 B3 ?? 12 and replace F4 BE 65 EA

Thanks in advance
